This article proposes a way of connecting two levels at which scholars have studied discursive practices from a normative perspective: on the one hand, local transactions-face-to-face arguments or dialogues-and broadly dispersed public debates on the other. To help focus my analysis, I select two representatives of work at these two levels: the pragmadialectical model of critical discussion and Habermas's discourse theory of politicallegal deliberation. The two models confront complementary challenges that arise from gaps between their prescriptions and contexts of actual discourse. In response, I propose a theory of argument cogency that distinguishes three kinds of merit: content, transactional, and public. Normative links between the two levels arise through the ways argument contents spread across multiple transactions in a social space whose structure and composition favor collective reasonableness.

Recent proposals for computer-assisted argumentation have drawn on dialectical models of argumentation. When used to assist public policy planning, such systems also raise questions of political legitimacy. Drawing on deliberative democratic theory, we elaborate normative criteria for deliberative legitimacy and illustrate their use for assessing two argumentation systems. Full assessment of such systems requires experiments in which system designers draw on expertise from the social sciences and enter into the policy deliberation itself at the level of participants.

By linking the conceptual and social dynamics of change in science, Kuhn’s Structure of Scientific Revolutions proved tremendously fruitful for research in science studies. But Kuhn’s idea of incommensurability provoked strong criticism from philosophers of science. In this essay I show how Raimo Tuomela’s Philosophy of Sociality illuminates and strengthens Kuhn’s model of scientific change. After recalling the central features and problems of Kuhn’s model, I introduce Tuomela’s approach. I then show (a) how Tuomela’s conception of group ethos aligns with Kuhn’s notion of paradigms as group commitments, and (b) how Tuomela’s distinction between I-mode and we-mode forms of collective intentionality can capture the shifting paradigmatic commitments in Kuhn’s model of change as a cycle of normal and revolutionary science. But Tuomela’s analysis does not rely on meaning holism, and thus does not involve the problematic notion of incommensurability that burdened Kuhn’s analysis

This article examines two approaches to the analysis and critical assessment of scientific argumentation. The first approach employs the discourse theory that Jurgen Habermas has developed on the basis of his theory of communicative action and applied to the areas of politics and law. Using his analysis of law and democracy in his Between Facts and Norms as a kind of template, I sketch the main steps in a Habermasian discourse theory of science. Difficulties in his approach motivate my proposal of an alternative approach that starts not with a theory of communicative action but with some broad categories drawn from argumentation theory. Using these categories, one can survey the various conceptions of scientific argumentation that have already emerged in the multi-disciplinary field of science studies. The more flexible, open-ended theoretic categories put one in a better position to'develop cooperative interdisciplinary studies that can inform the critical assessment of scientific argumentation

Despite the foment of the last two decades, philosophical ethics has fallen on hard times. While an increasing number of universalistic moral theories in the Kantian tradition limit themselves to questions of social and political justice, neo-Aristotelian theories of the good, like that of Bernard Williams, question the very possibility and desirability of a philosophical ethics. Viewed against this landscape, the program of discourse or communicative ethics, initiated by Karl Otto-Apel and then developed by Jürgen Habermas, is marked by its optimism. Although sharing a great deal with the Rawlsian tradition, discourse ethicists insist that justice is not “the chief virtue of social institutions” alone, but the privileged domain of the moral as such. And although agreeing with neo-Aristotelians’ skepticism—later repeated by Hegel against Kant—about decontextualized ethical theory, discourse ethicists nonetheless believe that an abstract formulation of the moral point of view that would be context-sensitive is still possible.

: For philosophers of science interested in elucidating the social character of science, an important question concerns the manner in which and degree to which the objectivity of scientific knowledge is socially constituted. We address this broad question by focusing specifically on philosophical theories of evidence. To get at the social character of evidence, we take an interdisciplinary approach informed by categories from argumentation studies. We then test these categories by exploring their applicability to a case study from high-energy physics. Our central claim is that normative philosophy of science must move beyond abstract theories of justification, confirmation, or evidence conceived impersonally and incorporate a theoretical perspective that includes dialogical elements, either as adjuncts to impersonal theories of evidence or as intrinsic to the cogency of scientific argumentation.

According to the standard version of discourse ethics (e.g. as formulated by Apel, Habermas, and others), the objectivity of moral norms resides in their intersubjective acceptability under idealized conditions of discourse. These accounts have been criticized for not taking sufficient account of contextual particularities and the realities of actual discourse. This essay addresses such objections by proposing a more realistic, contextualist 'principle of real moral discourse' (RMD). RMD is derived from a more comprehensive concept of objectivity that links intersubjective objectivity with a factual objectivity based in features of social conflicts and the moral problems they pose. To clarify RMD and make this approach more plausible, a number of theoretical and practical questions are addressed concerning the notions of reasonability and inclusivity entailed by RMD.

Central to the discourse ethics advanced by Jürgen Habermas is a principle of universalization (U) amounting to a dialogical equivalent of Kant's Categorical Imperative. Habermas has proposed that ?U? follows by material implication from two premises: (1) what it means to discuss whether a moral norm ought to be . adopted and (2) what those involved in argumentation must suppose of themselves if they are to consider a consensus they reach as rationally motivated. To date, no satisfactory derivation of ?U? from these two premises has been presented. Thus the present study attempts to show how one can, without begging the question, arrive at ?U? by assuming a suitable explication of these two premises, supplemented with a fairly innocuous assumption about the context of discourse. If the argument is sound, then ?U? brings both deontological and consequentialist intuitions together with a notion of solidarity that requires an intersubjective account of insight

In his Reflection Revisited, James Swindal interprets Habermas’s formal pragmatics as recasting the traditional philosophy of reflection in intersubjective, augmentation-theoretic terms. In this review essay, I consider some aspects of Swindal’s interpretation for situated moral criticism. I focus in particular on Swindal’s claim that moral discourse must be preceded by meta-discourses in which actors discuss issues related to the initiation of moral discourse. Although I reject Swindal’s arguments for the necessity of such meta-discourses, I provide further arguments for their theoretical possibility and practical desirability for a contextualized critical social theory.

Science advisory committees exercise complex collaborative expertise. Not only do committee members collaborate, they do so across disciplines, producing expert reports that make synthetic multidisciplinary arguments. When reports are controversial, critics target both report content and committee process. Such controversies call for the assessment of expert arguments, but the multidisciplinary character of the debate outstrips the usual methods developed by informal logicians for assessing appeals to expert authority. This article proposes a multi-dimensional contextualist framework for critical assessment and tests it with a case study of the controversies over reports issued by the Intergovernmental Panel on Climate Change. The case study shows (1) how the critical contextualist framework can illuminate the controversy and guide evaluation of the various arguments and counterarguments; (2) how cases of this sort open up avenues for fruitful interdisciplinary collaboration between argumentation theorists and other fields; and (3) where further work is required in argumentation theory

Of all the components that go into Jürgen Habermas's heroic efforts to elaborate the rational basis for critical social theory, his pragmatic theory of language—the "theory of communicative action" —is both the most important and the most ambitious. However, his arguments for this theory tend to be speculative, controversial, or even obscure at key points. This is unfortunate, given the potential significance of TCA as an account of the rationality of moral action. To remedy the situation, Joseph Heath carefully reworks—and significantly revises—the basic steps in Habermas's argument.

Contemporary critical theorists working in the Frankfurt School tradition have focused considerable attention on theories of deliberative democracy, which in general attempt to show how public argumentation can be both democratic and reasonable. In this context, political questions that involve or depend on science present an acute challenge, inasmuch as deliberation must meet especially demanding epistemic requirements. In this article, the author examines two past responses to the challenge, each of which failed to reconcile reasonableness and democracy: that of the scientists involved in policymaking in the 1940s in the United States, and that of Herbert Marcuse and the New Left in the 1960s. Both the scientists and Marcuse depended on general models of science-in-society that ultimately led them into elitist modes of argumentation. The author concludes by drawing some lessons for an interdisciplinary, argumentation-theoretic approach to science-related public argumentation. /// Pensadores críticos contemporâneos trabalhando dentro da tradição da Escola de Frankfurt prestaram considerável atenção a teorias sobre a democracia deliberativa, as quais em geral procuram mostrar até que ponto a argumentação pública pode ser simultaneamente democrática e razoável. Neste contexto, questões políticas que involvem ou dependem da ciência apresentam um sério desafio, tanto mais que a deliberação deve satisfazer requisitos epistémicos particularmente exigentes. No presente artigo, o autor examina duas respostas que no passado foram dadas a este desafio, cada uma das quais foi incapaz de reconciliar razoabilidade e democracia: a dos cientistas involvidos no desenho de políticas concretas durante os anos 40 nos Estados Unidos, e a de Herbert Marcuse e a Nova Esquerda durante os anos 60. Tanto os cientistas como Marcuse estavam dependentes de modelos genéricos de ciência-nasociedade os quais em última análise os conduziram a modelos elitistas de argumentação. O autor conclui extraindo algumas lições pertinentes para uma abordagem interdisciplinar, argumentativa e teorética à questão da ciência em sua relação com a argumentação pública.

What can rhetoric tell us about good arguments? The answer depends on what we mean by “good argument” and on how we conceive rhetoric. In this article I examine and further develop Jürgen Habermas’s argumentation theory as an answer to the question—or as I explain, an expanded version of that question. Habermas places his theory in the family of normative approaches that recognize (at least) three evaluative perspectives on all argument making: logic, dialectic, and rhetoric, which proponents loosely align with the three dimensions of product, procedure, and process, respectively (cf. Wenzel 1990; Tindale 1999). Habermas wants to integrate these perspectives in a conception of cogent argumentation that dispels ..

In Between Facts and Norms Jürgen Habermas works out the legal and political implications of his Theory of Communicative Action, bringing to fruition the project announced with his publication of The Structural Transformation of the Public Sphere in 1962. This new work is a major contribution to recent debates on the rule of law and the possibilities of democracy in postindustrial societies, but it is much more.The introduction by William Rehg succinctly captures the special nature of the work, noting that it offers a sweeping, sociologically informed conceptualization of law and basic rights, a normative account of the rule of law and the constitutional state, an attempt to bridge normative and empirical approaches to democracy, and an account of the social context required for democracy. Finally, the work frames and caps these arguments with a bold proposal for a new paradigm of law that goes beyond the dichotomies that have afflicted modern political theory from its inception and that still underlie current controversies between so- called liberals and civic republicans.The book includes a postscript written in 1994, which restates the argument in light of its initial reception, and two appendixes, which cover key developments that preceded the book.Habermas himself was actively involved in the translation, adapting the text as necessary to make it more accessible to English-speaking readers
